Hans lost all credibility with me when he backed the IPCC “data” on globull warming. If that vouches for his analytical skills he is either an idiot or on the take.
He commends the IPCC AR5 report as being “as good as science can do”. He says the difficulties of communicating the uncertainties in climate science are far greater than for other science communication problems that he has been involved in professionally, such as smoking and cancer. He goes as far to say that, in this regard, climate science will be a model for other sciences. That’s high praise indeed from one of the world’s expert science communicators.
